The invention relates to a sample plate and method for comparing corresponding grades before and after sanding of a steel plate, and belongs to the technical field of transformer detection devices and methods. According to the technical scheme, the device comprises a rusted steel plate sample plate and a steel plate sanding comparison sample plate, the rusted steel plate sample plate and the steel plate sanding comparison sample plate are made of steel plates, and the rusted grade of the steel plate sanding comparison sample plate is matched with that of the rusted steel plate sample plate. The method has the beneficial effects that the quality grade of the steel structural member such as the transformer oil tank after sanding is intuitively, quickly, simply, conveniently and effectively detected through the steel plate sample plates with different corrosion grades. 本发明涉及一种钢板打砂前后对应等级比对样板及方法，属于变压器检测装置及方法技术领域。本发明的技术方案是：包含锈蚀钢板样板和钢板打砂对比样板，所述锈蚀钢板样板和钢板打砂对比样板的材质为钢板，钢板打砂对比样板与锈蚀钢板样板的锈蚀等级相匹配。本发明的有益效果是：通过不同锈蚀等级的钢板样板，对变压
